Title (EN) RAPID DISSOLVING POLYMER COMPOSITIONS AND USES THEREFOR
(FR) COMPOSITIONS POLYMERES SE DISSOLVANT RAPIDEMENT ET LEURS UTILISATIONS
Abstract:
(EN) A particulate, free-flowing and rapid dissolving polymer composition is prepared by comminuting a high molecular weight thermoplastic or viscoelastic polymer (11) at a temperature below its glass transition temperature while maintaining the polymer in an inert environment. A finely divided, solid coating agent (12) is mingled with the comminuted polymer while maintaining the polymer particles in a cold and inert atmosphere. The particles of coating agent are formed into a protective shell (13) around each polymer particle by mixing the components while raising the temperature of the mixture. The polymer composition finds use as a drag reducing agent; as an anti-misting agent; to enhance the efficiency of oil skimming processes and devices; and for the preparation of polymer solutions for other uses.
(FR) Une composition polymère coulante, particulaire se dissolvant rapidement est préparée en broyant finement un polymère thermoplastique ou viscoélastique (11) de poids moléculaire élevé à une température inférieure à sa température de transition du verre tout en maintenant le polymère dans un environnement inerte. Un agent de revêtement solide, finement divisé (12) est mélangé avec le polymère finement broyé tout en maintenant les particules polymères dans une atmosphère froide et inerte. Les particules de l'agent de revêtement sont conformées en une enveloppe protectrice (13) autour de chaque particule polymère en mélangeant les composants tout en augmentant la température du mélange. La composition polymère trouve son utilisation en tant qu'agent réducteur de résistance de frottement, en tant qu'agent d'anti-exsudation, ainsi que pour améliorer le rendement de dispositifs et de procédés d'écumage du pétrole, et pour la préparation de solutions polymères destinées à d'autres utilisations.
